Elizabeth Githiiyu said her son David Githiiyu killed himself after a coach would not let him get on a bus to visit the University of Central Florida. Students were supposed to be seated and on the bus by 7 a.m., but David was dropped off at 7. He was seen knocking on the door by students and teachers, but the bus drove away.

"If he would have opened that door for my son, my son would be alive right now," Elizabeth Githiiyu told the Times-Union.

Elizabeth Githiiyu and David's father Ayub Njoroge are claiming that the school's employees did not follow a 2008 state law which requires investigation of any reported incidents of bullying, and that the parents of both the victim and the accused bully be notified.

After David's death, other students came forward and reported that he had been bullied for his last name and Kenyan heritage more often than his parents knew about.

The suit cannot be filed until February, which is six months after they are giving notice. The family's attorneys said a financial number has not been determined.

City of Jacksonville General Counsel Cindy Laquidara, who also serves as the school district's attorney, said her office would not comment on the letter, which they had not yet reviewed.
